had to google washlet, but yeah basically I think. It's a little attachment. I unscrewed the toilet seat, aligned this hard plastic bit with the bidet controls and the nozzle thing over the seat holes, then mounted the seat again. The water comes from my water line (?) which I removed from the toilet fill valve, added a T valve to in order to split the water, then ran the bidet water line to the split from the new T valve.
